Self-erecting tent

Abstract

A self-erecting tent, provided with at least three resilient frame elements ( 1, 2, 3 ) formed into endless loops which stretch a tent covering, with the tent in erected position, while at least two of the frame elements ( 1, 2 ) cross adjacent an underside of the tent, at least, with the tent in erected position.

1. A tent including:
 at least three individual resilient frame elements, integrated with a tent covering, which extend the tent covering when the tent is changed from a collapsed position to an erected position, wherein each of the at least three individual resilient frame elements is a respective endless loop, wherein a first said frame element and a second said frame element of the at least three individual resilient frame elements cross at two positions adjacent an underside of the tent, the two positions being on each of two opposite sides of the tent, at least with the tent in the erected position, while arch parts remote from each other of a third frame element of the three individual resilient frame elements extend at positions between an upper side of the tent and the underside of the tent, at least, with the tent in the erected position, wherein: 
 both the first frame element and the second frame element each include a top part located, with the tent in the erected position, adjacent the upper side of the tent; 
 both the first frame element and the second frame element include a lower part located, with the tent in the erected position, adjacent the underside of the tent; and 
 the arch parts remote from each other of the third frame element extend, with the tent in the erected position, at:
 lower positions than upper arch parts of the first frame element and second frame element, and 
 higher positions than lower arch parts of the first frame element and second frame element; and 
 
 wherein the tent, when in the erected position, is supported by the first and second frame elements and the tent covering such that the third frame element is suspended above a tent underside, and extends at all points along the third frame element, a non-zero distance from the tent underside. 
 
     
     
       2. The tent according to  claim 1 , wherein the third frame element extends at a distance from the crossings between the first frame element and second frame element, with the tent in the erected position. 
     
     
       3. The tent according to  claim 2  wherein the third frame element extends fully above a level of the crossings between the first frame element and second frame element, with the tent in the erected position. 
     
     
       4. The tent according to  claim 1 , wherein each of the at least three individual resilient frame elements is a substantially elliptical element. 
     
     
       5. The tent according to  claim 1 , wherein the tent can be brought from said erected position to a collapsed position and vice versa, the tent being substantially circular in a collapsed position. 
     
     
       6. The tent according to  claim 1 , wherein the tent is substantially mirror symmetrical relative to a central transverse plane of the tent. 
     
     
       7. The tent according to  claim 1 , wherein the tent is provided with a two layer bottom defining a bound space for placing a mattress therein. 
     
     
       8. The tent according to  claim 1  wherein the third frame element extends fully above a level of the crossings between the first frame element and second frame element, with the tent in the erected position. 
     
     
       9. The tent according to  claim 1  wherein the first frame element and the second frame element provide a primary source of force suspending the tent covering. 
     
     
       10. The tent according to  claim 9  wherein the third frame element is suspended above the tent underside by a suspending force provided by the first frame element and second frame element, and applied to the third frame element via the tent covering. 
     
     
       11. The tent according to  claim 1  wherein relaxation of the third frame element is counteracted, while the tent is in the erected position, by forces exerted by the tent covering. 
     
     
       12. The tent according to  claim 1  wherein the first, second and third frame elements are constrained in their relative partially relaxed positions, while the tent is in the erected position, by the tent covering, thereby avoiding a need for frame coupling elements that are not permanently connected to the tent.
